The motor core stamping process involves the fabrication of stator and rotor cores, which are essential components in electric motors. Given the complexity of these components, maintaining high-quality standards throughout the stamping process is crucial. Quality control begins with the selection of raw materials, which must meet specific criteria to ensure they can withstand the demands of the final application. The properties of the materials used in motor core stamping directly affect the performance and efficiency of the motor, making material inspection a fundamental step in the quality assurance process.
